To all whom it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, a citizen of the UnitedStates, residing at Newton,in the county of Middlesex and State ofMassachusetts, haveinvented a new and useful Improvement in HeelCompressing and Loading Machines, ofwhich the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part vof this specification, in explaining itsnature. 1

The invention relates to an apparatus for compressing and loadingheel-blanks comprising the rotary cylinder carrying one or morecompressing-dies and former for each' die movable in relation to itscavity by means of a suitably shaped bearing abutment, against which theformer is brought in con-. tact as the die is rotated; also to anarrange ment within thecylinder carrying the dieblocks or apparatus forpricking holes in the heel-blank from the die.

It further relates to various details ofconstruction and organization,all of which will hereinafter be described.

In the drawings, Figure 1 is a view in front elevation of the centraland upper parts of the machine. Fig; 2 is a vertical section-0f the saidcentral and upper parts of the ma chine, taken from side to sidethereof. Fig. 3 is a view in elevation of one side of the cen- 'tral andupper parts of the machine. .Fig. 4-

is a vertical section thereof taken from front to back of the machine.

A is the base of the machine. a, is the shaft to which preferably poweris communicated. 1

B is a cylinder provided with bearings 1) upon the brackets b 19 whichbrackets are" bolted to the bed of the base and have inwardextendingcircular sections b which serveas bearing pieces or trunnions upon whichthe cylinder B is rotated. The cylinder has the cavity 0, and acrossthis cavity there extends a shaft 0, which has bearings in the bracketsb b at o 0 and which carries a cam c for operating the gang of awlsc thegang of driV-' ers c and the ejector c". The shaft 0 is ro-j tated bymeans of the gear c upon one end thereof, the intermediate gear 0 andthe gear 0 upon the shaft a.

The cylinder B isrepresented as carrying the four die-blocks D, each ofwhich has the die-cavity d and the perforations d, through which theawls, nails, and drivers are moved, and the hole d through which theejector 0 passes in throwing the loaded heel-blank from the die. Thesedie-blocks, are fastened in re cesses or holes formed in the cylinder inany desired way, and; there is attached to the cylinder, to be rotatedwith it, a former E for each die-block. This former is removably securedto a former-carriage E, which comprises a block e carrying anantifriction-roll e, and preferably secured to the cylinder by means ofa link e pivoted at e to a log efl and connected by a pivot c with theblock e. The block has bearings e for the shaft of the roll e'l (SeeFig. 2.)

F is the pressure-applying plate or abutment. It is secured to the baseof the machine and has a surface f which is placed eccentrically inrelation to the circle or path upon which the outer edge of the cylinder13 rotates to cause the former-carriage E and the formers to be movedgradually inward as they travel or move in relation to the same, the,rolls 6 of course bearing against. the said surface 7 in successiveorder. The awls c .are mounted upon a block 0 which is re- This slide isarranged tobe reciprocated in a suitable bearin g-hole in thecross-plate e by means of the cam-groove c? in the cam-disk 0 The slidealso has a bearing upon the shaft 0, the end of the slide being foiimedas a yoke to straddle the shaft. The-drivers c are also re movablysecured to a slide cf. This is also reciprocated by the cam-groove 6and, like the slide 0, it has a yoke which straddles the shaft 0. Theslide 0 also has a bearing in the cross-plate 0 The ejector is mountedupon a slide-block and is moved by the cam projection c outwardly, andis returned by the spring 0 Nails are fed v to the holes or perforationsof the die by means of the nail-carrier G, which is automatically movedthrough the hole g in the bracket 1) to a po sition to deliver nailsbeneath the driver and into the holes of the die-block,which shall thenICO be beneath it. h It may be automatically moved in any desired way,and I have represented arm g the right-angle lever g pivoted at g andconnected at its upper end by means of a stud g with a slotted hanger 9attached to the plate g carrying the nail-carrier. The nail-carrier issupplied automatically with nails from the nail-supplying apparatus H,which preferably consists essentially of these elements: A number ofpairs of nail pointing and severing rolls I-l; wire-feeding rolls h,adapted to feed a number of Wires and to make simultaneously, orpractically simultaneously, a nail from the end of each wire; anail-receiving block 7t, which is automatically moved to bring its holesin register with the throats through which the nails are delivered fromthe rolls, and which is automatically returned to deliver its nails tothe distributer I1 and the said distributor adapted to receive the nailsfrom the nail-receiving block and to deliver them to a nail-carrier.These features are described in an application for Letters Patent of theUnited States of even date herewith, and I would say I prefer to usethis form of automatic nail-supplying device because, by making nailsfrom a number of wires, 1 am enabled to produce a large number veryquickly, substantially as quickly as they are needed for use in themachine. I would not be understood, however, as limiting myself to thisparticular form of nail-supplying mechanism.

Each former-carriage E preferably has in addition to the roll 6 a roll mattached to one end of the shaft of the roll a and which serves inconnection with a side guide M extending from the point 712 to the pointm (see Fig. 4) to hold the former and former-carriage open or awayfromthe die during the movement of each die from its lowest position to verynearly its highest position, so that the die is open or uncoveredautomatically both to permit the loaded heel-blank to be ejectedtherefrom and also the insertion of a new blank to be formed and loaded.

The machine preferably is organized to stop at each quarter-revolutionofthe die-cylinder. The cylinder is represented as alternately rotatedand brought to rest by meansof a feedpawl N, mounted upon the lever n,which is pivoted upon the shaft 0, the crank 71/, and

the connecting-rod 01 the crank imparting to the lever an oscillating orreciprocating movement, first causing the pawl 91 to engage with one ofthe four notches n in the side of the cylinder and then moving itforward a quarter of a revolution, so that for every full revolution ofthe crank 71' the diecylinder is moved a quarter-revolution in half thetime of the revolution of the crank and is at rest for the remainder ofthe time. I would say that I do not confine myself to this particularmechanism for rotating the cylinder but may use any mechanicalequivalent therefor.

In operation the heel-blanks are placed in thedies in successive order,and upon the rotation of the cylinder the former is caused to be movedforcibly against one end of the same by the movement of the cylinder inrelation to what may be called the curve compressing Wedge or cam f, andthis movement of the dies to secure the compression of the heelblanksbrings each compressed heel-blank in turn in line with the gang of awlsand with the nail-loading devices, and each heel-blank is firstsubmitted to the operation of the awls 0 which while the die-cylinder isat rest makes a rapid movement through the holes in the die-block andpricks the heel-blank while it is under compression. The cylinder isthen moved, bringing the compressed but unpricked blank in line with theawls, while the compressed and pricked blank is moved into positionto beloaded, and the cylinder coming to rest the awls operate to form theholes in one blank while the drivers are actu ated to drive theattaching-nails into another blank. The nails have previously beenautomatically fed by the nail-carrier into a position beneath thedrivers. A further rotation of the cylinder causes the heel-former to bereleased from the die and to be automatically removed from it to openthe die and bring a loaded heel-blank before the ejector, a pricked andcompressed heel-blank beneath the drivers, and a compressed heel-blankin line with the awls, and at the next operation of the machine a loadedheel-blank is ejected from the die, a compressed and pricked heel-blankis automatically loaded, and a compressed heelblank pricked.

It will be observed that the pressure upon the heel-blank from the firstaction of the former during the prickingjby the awls'and the loading bythe drivers is continuous, and that it may be varied 'as to intensity byvarying the inclination or relation of the wedge or cam surfacef inrelation to the cylinder; that this produces a very powerful and slowand continuous compression which produces a Very-nicely compressedheel-blank. It will be observed, further, that the awls and drivers areworked from the interior of the diecarrying cylinder.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1.
